Description
BRIEF DESCRIPTION OF THE DRAWINGS
[0085] Other objects and features of the present disclosure will become apparent from the following detailed description considered in connection with the accompanying drawings. It is to be understood, however, that the drawings are designed as an illustration only and not as a definition of the limits of the present disclosure.
[0086] In the drawings, FIGS. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52 and 53 show various views of a formwork support system and its components in different stages of the assembly of the formwork support system.
[0087] FIGS. 54, 55 and 56 show views of components of another embodiment of a formwork support system.
DETAILED DESCRIPTION OF THE DRAWINGS
[0088] FIG. 1 shows a formwork support system 1 for support of a number of formworks, in particular formwork sheets (panels) of plywood 2 (schematically illustrated in FIG. 6). Such shoring and decking system is used for pouring generally horizontally extending concrete slabs, such as ceilings or floors.
[0089] The formwork support system 1 comprises a plurality of support props or support posts 3, a plurality of longitudinal beams, i.e. longitudinal carriers or stringer frames, 4 supported on the support props 3 and a plurality of transverse beams, i.e. crossbars or joist frames, 5 either supported on the support props 3 or on the longitudinal beams 4. The transverse beams 5 extend transversely, optionally perpendicularly, to the longitudinal beams 4. As can be seen from the drawings, the longitudinal beams 4 and the transverse beams 5 are arranged and connected to each other on the same vertical level thereby forming one single horizontal support area for the formworks.
[0090] Each support prop 3 has a leg 6 with a lower leg part 6a, an upper leg part 6b and a connecting device 7 for securing the upper leg part 6b in a plurality of vertical positions with respect to the lower leg part 6a. In the shown example, the connecting device 7 has a bracket which may be inserted into one of a plurality of vertically spaced attachment openings of the support prop 3. Furthermore, each support prop 3 comprises a head member 8 mounted on an upper end of the upper leg part 6b of the leg 6. The leg 6 of the support prop 3 further has a floor support plate 9 at a lower end of the lower leg part 6a.
[0091] As can be best seen in FIGS. 2 to 4, each head member 8 at its upper end has a support plate 10 with an upper side 11 for supporting the formwork 2 thereon. In the shown embodiment, the support plate 10 has a constant wall thickness (i.e. extension in vertical direction). More generally speaking, the support plate 10 has a plane, horizontally extending upper side 11, whereas the shape of the support plate 10 below the upper side 11 may vary. The support plate 10 has at least one recess 12 formed in a side edge 13 thereof. This recess 12 accommodates an edge portion 14 of the respective end of the longitudinal beam 4. The edge portion 14 of the longitudinal beam 4 and the recess 12 have corresponding extensions in direction perpendicular to the longitudinal axis 15 of the longitudinal beam 4 (illustrated in FIG. 7) such that the edge portion 14 snugly fits into the recess 12 of the support plate 10 of the head member 8. In the assembled state, the snug fit between the edge portion 14 of the longitudinal beam 4 and the recess 12 of the head member 8 prevents tilting of the longitudinal beam 4 with respect to its longitudinal axis 15. Each longitudinal beam 4 comprises a main longitudinal section 16 extending between the opposite ends of the longitudinal beam 4. In the assembled state, the connection of the longitudinal beam 4 with the head member 8 results in a top side 17 of the main longitudinal section 16 of the longitudinal beam 4 being arranged flush with the upper side 11 of the support plate 10 of the head member 8.
[0092] In the shown embodiment, the support plate 10 comprises one recess 12 in each one of the four sides of the support plate 10 which has a square ground shape in top view. In this embodiment, neighboring recesses 12 are arranged perpendicular to one another. In this way, the head member 8 forms a crosshead for connection with four longitudinal beams 4 and/or transverse beams 5.
[0093] In the assembled state, the end of the longitudinal beam 4 extends downwards from the recess 12 in the support plate 10 of the head member. Furthermore, the head member 8 comprises an intermediary plate 40 arranged between the upper end of the head member 8 and the lower end thereof. The intermediary plate 40 comprises clearances 41 corresponding to the recesses 12 in the support plate 10 (see FIG. 5, 6).
[0094] The releasable connection between the longitudinal beam 4 and the head member 8 further comprises a support device 18 (see FIG. 3) for supporting the respective end of the longitudinal beam 4 on the head member 8 in a vertical direction. In the shown embodiment, the support device 18 comprises a pin 19 and a groove 20. The pin 19 is arranged on the longitudinal beam 4 below the edge portion 14 of the head member 8. The groove 20 is arranged on the head member 8 below its support plate 10.
[0095] The support device 18 serves for vertically supporting the longitudinal beam 4 on the head member 8, while the form-fit between the edge portion 14 of the longitudinal beam 4 and the recess 12 of the support plate 10 of the head member 8 prevents tilting of the longitudinal beam 4 with respect to its longitudinal axis.
[0096] As can be seen from FIGS. 1 to 3, each transverse beam 5 has opposite end regions 21 that snugly fit into the recesses 12 of the head member 8. Furthermore, each transverse beam 5 comprises a bolt 22 that connects to channels 23 of the head members 8. Bolt 22 and channel 23 for attaching the transverse beam 5 to the head member 8 may be identical to pin 19 and groove 20 for attaching the longitudinal beam 4 to the head member 8. For example, two longitudinal beams 4 and two transverse beams 5 may be connected to the same head member 8. As can be seen in FIG. 45 to FIG. 50, transverse beam 5 and longitudinal beam 4 may be lowered on the head members 8 of the respective support props 3 from a position above head member 8.
[0097] As can best be seen from FIGS. 7, 14 and 16, the longitudinal beams 4 each comprise at least one downwardly projecting hook element 24 and a slot 25 extending in longitudinal direction 15 of the longitudinal beam 4. In this way, the hook element 24 of one longitudinal beam 4 can be connected to the slot 25 of another longitudinal beam 4. In the shown example, the longitudinal beam 4 comprises two hook elements 24 spaced in direction perpendicular to the longitudinal axis 15 and a bracing 26 connecting the two hook elements 24.
[0098] Furthermore, the longitudinal beam 4 comprises a downwardly projecting stop element 27. As can best be seen from FIGS. 11, 13 and FIGS. 15, 17, respectively, the stop element 27 facilitates assembly of the formwork support system 1. First, when connecting a longitudinal beam 4 arranged in an inclined interim mounting position (FIG. 11, FIG. 13) to one of the head members 8, the stop element 27 of the longitudinal beam 4 abuts on the head member 8 of prop 3 to facilitate assembly and improve safety. Second, when connecting a first longitudinal beam 4 arranged in an inclined interim mounting position to a second longitudinal beam 4 arranged in a horizontal final position by means of the hook element 24 of the first longitudinal beam 4 and the slot 25 of the second longitudinal beam 4, the stop element 27 of the first longitudinal beam 4 abuts on a lateral face of the second longitudinal beam 4 (FIG. 15, FIG. 17). In the final position, the stop element 27 of the longitudinal beam 4 is spaced apart from the head member 8 or the other longitudinal beam 4, respectively.
[0099] As can be seen from FIGS. 18 to 25, the transverse beam 5 at its end regions comprises stoppers 28, which may be identical to the stop elements 27 of the longitudinal beams 4. When attaching the transverse beam 5 to the head member 8, the transverse beam 5 is first arranged in an interim mounting position extending downwardly towards its free end (see FIG. 19 and FIG. 21) by connecting the bolt 22 of the transverse beam 5 to the channel 23 of the head member 8. In this inclined interim mounting position, the stopper 28 of the transverse beam 5 bears against the head member 8. By lifting the transverse beam 5 from the interim mounting position into its horizontally extending final position, the stopper 28 is placed at a distance from the head member 8.
[0100] Furthermore, the transverse beam 5 comprises a downwardly projecting catch element 29 for connection with the slot 25 of the longitudinal beam 4 (see FIGS. 22 to 25). The stopper 28 of the transverse beam 5 bears against a lateral side of the longitudinal beam 4 when the transverse beam 5 is arranged in an inclined interim mounting position (see FIGS. 23 and 25).
[0101] The catch element 29 of the transverse beam 5, the hook element 24 of the longitudinal beam 4 and the slot 25 of the longitudinal beam 4 have a shape which provides for an adequate pivoting range in the slot 25.
[0102] As can best be seen from FIGS. 8, 9, the transverse beam 5 comprises a first catch element 29a at a first end region 21a of the transverse beam 5 and a second catch element 29b at a second end region 21b of the transverse beam 5. In the assembled state, each of the first catch element 29a and the second catch element 29b is connected to the slots 25 of the longitudinal beams 4. For facilitating assembly of the formwork support system 1, the first catch element 29a and the second catch element 29b are spaced apart in direction perpendicular to a longitudinal direction 30 (see FIG. 9) of the transverse beam 5. In view of increasing stability of the arrangement, the transverse beam 5 further comprises a first abutment element 31a at the first end region 21a of the transverse beam 5 and a second abutment element 31b at the second end region 21b of the transverse beam 5. The first catch element 29a and the second catch element 29b extend below the first abutment element 31a and the second abutment element 31b. The first catch element 29a at the first end region 21a and the second abutment element 31b at the second end region 21b are arranged at the same horizontal position in direction perpendicular to the longitudinal direction 30 of the transverse beam 5. Likewise, the first abutment element 31a at the first end region 21a and the second catch element 29b at the second end region 21b are arranged at the same horizontal position in direction perpendicular to the longitudinal direction 30 of the transverse beam 5. In other words, the horizontal position of the catch elements and the abutment elements on the opposite end regions of the transverse beam is interchanged. This arrangement facilitates mounting of the transverse beams 5 to the longitudinal beams 4 when erecting and stripping the formwork support system, which will be described below.
[0103] As can be seen from FIGS. 14 to 17 and FIGS. 22 to 25, the slot 25 of the longitudinal beam 4 is delimited by a flange 43 with a top side 44 and an undercut (back taper) 45.
[0104] The top side 44 of the flange 43 is arranged for supporting the pin 19 of the longitudinal beam 4 in its final (support) position (see FIG. 16). Furthermore, the top side 44 of the flange 43 is arranged for supporting the bolt 22 or the first abutment element 31a or second abutment element 31b of the transverse beam 5.
[0105] On the other hand, the undercut 45 of the flange 43 is arranged for holding the hook element 24 of the longitudinal beam 4 in its inclined interim mounting position (see FIG. 15, 17) and for holding the catch element 29 of the transverse beam 5 in its inclined interim mounting position (see FIG. 23, 25)
[0106] Furthermore, the transverse beam 5 at each end region 21 comprises at least one shoulder 32. In the shown example, two shoulders 32 are provided on either end region 21. A first shoulder 32a is formed by a projection of the first catch element 29a, a second shoulder 32b is formed by a projection of the first abutment element 31a.
[0107] As can best be seen from FIG. 5, FIG. 6 in conjunction with FIG. 27 and FIG. 28, the head members 8 each comprise at least one upwardly projecting holding element 33 with a hook formed at its upper (free) end. In the shown example, two holding elements 33 are provided on either side of the head member 8. Thus, each head member 8 has a total of eight holding elements 33. As can be seen from FIG. 27 and FIG. 28, the holding elements 33 are used for holding the pin 19 of the longitudinal beam 4 when the support prop 3 is brought from an inclined interim position with the lower end of the leg 6 supported on a floor 42 of a building under construction (see FIG. 27, left support prop 3) to an upright support position (see FIG. 27, middle and right support prop 3). Lifting the beams into their horizontal support position for connecting with the head member 8 can, hence, be done without the need to lift up the heavy weight of the beam and the prop 3.
[0108] As can best be seen from FIG. 5, 6, the head member 8 comprises a lowering device 34 for lowering a middle part 8a of the head member 8 with respect to the support plate 10. Thus, the middle part 8a may be lowered from the shown upper casting position towards the upper end of the leg 6 to a lower stripping position (not shown). The middle part 8a is arranged for supporting at least one of the longitudinal beam 4 and/or the transverse beam 5. For this purpose, the middle part 8a, in the shown example, has the grooves 20 for accommodating the pin 19 of the longitudinal beam 4 or the bolt 22 of the transverse beam 5. The lowering device 34 enables a drop head function, which is known in the prior art. In the shown example, the lowering device 34 comprises a wedge 35 which may be moved from a locking position (shown in FIG. 5, 6) to a release position (not shown) for lowering the middle part 8a of the head member 8. In the lower stripping position, the middle part 8a of the head member 8 is supported by an attachment plate 37 at a lower end of the head member 8 which is mounted on the upper end of the leg 6. The support plate 10 rests in place for supporting the formwork panel and the concrete slab positioned thereon.
[0109] FIG. 26 shows the formwork support system 1 during assembly. In this example, one longitudinal beam 4 and one transverse beam 5 are connected to the existing arrangement.
[0110] FIGS. 27 to 31 illustrate further mounting of a longitudinal beam 4 by means of one of the support props 3. First, one end of the longitudinal beam 4 is connected to the head member 8 of a support prop 3 installed before. Then, the other end of the longitudinal beam 4 is connected to the support prop 3 by placing the pin 19 in the holding element 33 which adjoins the groove 20. The support prop 3 may then gradually be lifted to its upright final position (see. FIGS. 30, 31).
[0111] FIGS. 32 to 34 illustrate further the mounting of a transverse beam 5 to the formwork support system 1. For this purpose, one end region of the transverse beam 5 is connected to one of the longitudinal beams 4. Then, a tool, such as a fork instrument 38, is used to lift the transverse beam 5. Due to the interchanged position of the catch elements and abutment elements at the opposite end regions of the transverse beam 5, the end region of the transverse beam 5 supported with the fork 38 may be pivoted sideward to connect to the other longitudinal beam 4, see arrow 36 in FIG. 33 and arrow 39 in FIG. 34. Consequently, the beams 5 can be put into place without the need of lifting them up beyond the top side of the formwork support system 1, i.e. the horizontal plane defined by the top side 17 of the transverse beam 5 and upper side 11 of the head member 8 of the prop 3. This is particularly advantageous when it comes to the stripping of the longitudinal beams 4 and transverse beams 5 since the completed concrete slab may not provide for sufficient room beyond the top side of the longitudinal beams 4 and transverse beams 5, despite the lowering of the beam arrangement by means of the lowering devices 34.
[0112] As can additionally be seen from FIGS. 32 to 34 the transverse beams 5 can be held in an interim (intermediary) mounting position in one of the slots 25 of the longitudinal beams 4 by means of the catch elements 29, the abutment elements 31 and the stoppers 28 of the transverse beam 5 and the flange 43 having the undercut 45 of the longitudinal beam 4, into which one of the catch elements 29 can be hooked (as can also be seen in FIG. 25). Two or more transverse beams 5 can be connected to and suspendedby their end regionsfrom one of the longitudinal beams 4. Their interim free end regions can, then, be lifted up one after the other until all transverse beam 5 are arranged in their horizontal, final support positions. Thus, the formwork support system 1 may be installed by one worker in a fast manner. Depending on its height the formwork support system 1 may even be installed without the tool shown in the drawing.
[0113] As shown in FIG. 35, 36, any transverse beam 5 that is connected to two support props 3 may be lifted from a self-supporting interim mounting position (as shown in FIG. 21) to a horizontal support position (as shown in FIG. 20) in the same way as longitudinal beam 4 (see FIGS. 28 to 31). Thus, holding element 33 of another support prop 3 is used to catch the bolt 22 on the second end region of transverse beam 5. The lower end of support prop 3 is supported on the floor while support prop 3 is moved from an inclined position to an upright (vertical) position thereby lifting transverse beam 5 into the horizontal support position.
[0114] As indicated in FIG. 14, 16, an upper section 46 of the edge portion 14 of the second longitudinal beam 4 in its horizontal position is spaced by a first gap 47 from an outer edge 48 of the top side 17 of the first longitudinal beam 4 to which the second longitudinal beam 4 is connected. The first gap 47 ensures that the longitudinal beams 4 may not only be arranged in the shown horizontal support positions, but also without blocking in inclined support positions (not shown) when the support props 3 are adjusted to different lengths for pouring inclined concrete slabs.
[0115] In the same fashion, a second gap 48 is formed at the end regions 21a, 21b of the transverse beams 5 being connected in a horizontal position to the longitudinal side of the longitudinal beam 4 (see FIG. 22, 24). Such gaps may also be provided for the connection of the longitudinal beam 4 and/or the transverse beam 5 to the head member 8 in a horizontal position, respectively (FIG. 2, 3).
[0116] As mentioned before, transverse beam 5 comprises shoulder 32 which ensures the disconnection of the transverse beam 5 from the formwork panel 2 during stripping of the formwork by actuation of head member 8 of support prop 3 (see FIG. 5, 6). FIGS. 37 to 40 show one of the transverse beams 5 arranged between two support props 3. FIGS. 41 to 44 show one of the transverse beams 5 connected between two longitudinal beams 4. In the latter example, shoulder 32 extends horizontally below a lateral edge at the top side 17 of longitudinal beam 4. During stripping of the formwork, i.e. removal of formwork panel 2 through actuation of the head members 8 of the corresponding support props 3 (see horizontal arrow in FIG. 37), transverse beam 5 may still be connected to the formwork, for example by means of nails projecting through the formwork panel 2 into a wooden strip on top of transverse beam 5. When lowering the middle part of head member 8 (see vertical arrow in FIG. 38), shoulder 32 of transverse beam 5 comes into contact with an impact area 49 of longitudinal beam 4 extending below the top side of the longitudinal beam 4 to ensure lowering or movement of the transverse beam 5 together with the longitudinal beam 4 and to prevent deficient stripping of the formwork system. In the former example, shoulder 32 extends horizontally below a flange portion 50 of head member 8 which serves as an impact region for shoulder 32 during stripping of the formwork.
[0117] As can be seen from FIGS. 48 to 50, longitudinal beam 4 may be mounted to a head member 8 of a support prop 3 by lowering longitudinal beam 4 from above the head member 8 vertically downwards, thereby passing hook element 24 and bracing 26 of the edge portion 14 of the longitudinal beam 4 through the recesses 12 of the head member 8. The lower section of the edge portion 14 having the hook element 24 and the bracing 26 is extending beyond the upper section of edge portion 14. Thus, the beam 4 is then moved slightly towards the (middle part of the) head member 8 into the space provided (and confined) by the support plate 10 of the head member 8 until pins 19 on opposite ends of longitudinal beam 4 are accommodated by correspondingly shaped grooves 20 provided in the head members 8. The edge portions 14 of longitudinal beam 4 at its opposite ends are connected to recesses 12 of head members 8 of the other (neighboring) support prop 3, which may laterally be tilted so that the edge portions 14 of the opposite ends of the longitudinal beam 4 can pass through the recesses 12 of the head members 8 of the other neighboring support prop 3. Likewise, transverse beam 5 may also be connected to head members 8 by lowering transverse beam 5 onto head members 8 of support props 3 until bolts 22 of transverse beam 5 are inserted into channels 23 of head members 8.
[0118] As can be seen from FIG. 51, formwork support system 1 may further comprise a wooden transverse beam 51 that may be supported on top side 44 of flange 43 of longitudinal beam 4.
[0119] As can be seen from FIGS. 52, 53, a double-T-profiled transverse beam 52 may be used in formwork support system 1. The end region of double-T-profiled transverse beam 52 is formed as in transverse beam 5 described above so that double-T-profiled transverse beam 52 may be hooked into slot 25 of longitudinal beam 4 as explained above. As a matter of course, a conventional double-T-profiled beam having an appropriate shoe (with hooking means able to be received by the slot 25 and a bolt to support the conventional beam on the flange 43 of the longitudinal beam 4) releasably or non-releasably mounted on its ends, of any other shape as shown in FIG. 52, 53, may be used.
[0120] FIGS. 54 to 56 show another embodiment of the head member 8 and end region 21 of the transverse beam 5. The same reference numbers are used for identical or functionally identical parts. In distinction from the embodiment of FIG. 5 and FIG. 6, in this embodiment the head member 8 at each side comprises but one upwardly projecting holding element 33 with a hook formed on its upper free end and a groove 20 or channel 23 for receiving the pin 19 of the longitudinal beam 4 or the bolt 22 of the transverse beam 5. The holding elements 33 as well as the grooves 20 or channels 23 are positioned centrally on each of four sides of a main body of the head member 8. The holding elements 33 are aligned with the recesses 12 of the support plate 10. According to the embodiment of FIG. 5, 6, two holding elements 33 are arranged at lateral edges on each side of the main body of the head member 8. It is apparent, that longitudinal beam 4 when attached to the alternative head member 8 of FIG. 54, 56 shows the same (end) configuration in the same manner as transverse beam 5, in that the edge portion 14, in particular its hook elements 24, of the longitudinal beam 4 are arranged outside holding elements 23.
[0121] As can be seen from FIG. 56, the catch element 29 and the abutment element 31 of the end region 21 of the transverse beam 5 arewhen connected to the head member 8arranged outside the groove 20 (or channel 23) formed in the holding element 33. Therefore, the bolt 22 of the end region 21 of the transverse beam 5 may be shorter in length as compared to the embodiment shown in FIG. 8; the catch element 29 of the end region 21 of the transverse beam 5 (FIG. 55) may be smaller in width (FIG. 55). Since the end region 21 is received in the recess 12 of the support plate 10, sideward tilting of the beam 5 is prevented.
[0122] It is apparent to the person skilled in the art that multiples of the constituting elements of the formwork support system 1 described herein may be used to cover wider areas of a construction site and/or increase stability of the formwork support system. For example, a greater number of support props 3, longitudinal beams 4 and transverse beams 5 may be deployed.
